Anu Engineer commented on HDFS-9593:
------------------------------------

Thanks you for the patch.  I would have +1-ed it, but looking at the tests it 
looks like we did not really run any tests in the Jenkins run.
So I am little hesitant to +1 this.  Could you please add a test -- Something 
every simple so that we know that this code is actually exercised somewhere. 

Also it would be a good idea to assign this patch to yourself so that other 
contributors know that you are working on it.

> Please find attached a code review of BlockTokenIdentifier.
> The only real change is using an explicit StringBuilder instead of an 
> implicit one so that the internal buffer may be set more appropriately and 
> checking for zero-length string instead of comparing to an empty string.  The 
> relatively small default buffer of 16 bytes would need to be expanded several 
> times to fit the incoming string.
